4.9 hydraulic System maintenance
Hydraulic System
The hydraulic pumps operate at very high pressure
and have specific maintenance requirements. You
should perform all recommended maintenance ac-
cording to the pump manufacturers’ specifications.
Hydraulic fluid should be changed and the tank
flushed on a regular schedule in accordance with
Hog Technologies and the hydraulic component
manufacture’s recommendations. Hog Technolo-
gies recommends changing the fluid at least once
every 600 hours.
CAUTION
NEVER MIX BRANDS OF HYDRAULIC OIL. THE ADDITIVES
WILL NOT BE COMPATIBLE CAUSING BLINDING OF THE
FILTER.
YOUR TRUCK HAS BEEN FILLED AT THE FACTORY WITH
CHEVRON BRAND AW68. IT IS VERY IMPORTANT TO USE
THE SAME BRAND WHEN ADDING OIL.
Make sure the cutting system is shutdown and
the truck is in the service position. Then use the
following procedures to maintain the hydraulic
system.
Daily Inspection and Maintenance
• Check the hydraulic fluid level each day or im
-
mediately following the repair of a blown hose,
leaking fitting or any hydraulic system service.
• Inspect all hoses, fittings, valves and seals for
leaks daily. Repair or replace leaking or mal-
functioning components before operating the
system.
•
Check the pressure indicator or gauge at the
filters with components operating. Make sure
it is well within the green zone. Change the
filters when the indicator moves near or into
the red zone.
•
Monitor cooling fan operation and make sure
fans are activating when necessary, sound
normal and pull a strong flow of air through
the coolers.
Refer to the Maintenance Matrix in this section for
fluid specifications.
